Warmouth : http://www.landbigfish.com/fish/fish.cfm?ID=65

Though they do resemble each other ... I think the Warmouth is a little more brightly colored (looks like it has "warpaint" on it :D ), whereas the Rock Bass is more darker colored (browns & blacks).
The Rock Bass have six anal fin spines which helps distinguish them from the Warmouth, which has three.
